Direct Drive Blast Wheels

Industrial Associates and Bronco Blast Equipment pioneered the direct drive airless shot blast wheel in the early 1980s. Our standard direct drive blast wheels are powerful, heavy-duty and easy to service. They clean faster, save significant costs and will increase productivity in your shot blasting operation.

Efficient Design

Our standard 12″, 15″ and 16″ diameter, 3600 RPM wheel assemblies:

  • Reduce cycle times by 50% or more
  • Can clean twice as fast as the 1800 RPM designs of the past

Wheel Housing

  • Fabricated from 1/2″, 11-14% manganese steel
  • Lined with heavy-duty, cast liners for extended wear life

Cleaning Power

Higher velocity means faster cleaning.

  • Abrasive thrown at 245 to 325 feet per second
  • Faster line speeds
  • Shorter cycle times
  • Lower abrasive flow rate prevents unnecessary wear on material handling systems and consumes less abrasive per blasting hour


  • Energy-efficient Baldor motors C-face mount to the wheel housing and bolt directly into a recessed flange ring
  • Proper alignment of wheel parts is ensured upon reassembly
  • Overhung shaft loads are far less than traditional foot mount designs
  • Reduced risk of motor bearing failure vs. traditional foot mount designs

Bronco direct drive blast wheel features include:

  • Front access plate for easy maintenance access
  • Single-sided, 8-bladed with dead-end dovetail slots for blade retention
